NASA Wants Standards for Evaluating Claims of Extraterrestrial Life

Scientists aim to help the public judge: Is this discovery believable or not?

This rare picture of an exoplanet (called 2M1207B) shows a red world several times Jupiter’s size orbiting a brown dwarf much smaller and dimmer than our sun. LUVOIR is after more elusive targets: small, rocky planets around bright stars.

The Space Telescope That Could Find a Second Earth

What will it take to capture images of a distant world capable of harboring life?

Spacesuit builders ILC Dover and Collins Aerospace showed off their privately developed Astro exploration suit at an event on Capitol Hill last July. NASA may need help from such commercial ventures if it hopes to make a 2024 moon landing.

Designing a Moon Suit for the 21st Century

The date for the next lunar landing has been set, but the astronauts don’t have a thing to wear.

‘Oumuamua,  shown here in an artist’s concept, was the first object seen to enter our solar system from interstellar space. Could it be an artifact sent by some distant civilization?

Signs

We've been listening for extraterrestrials. Now we're starting to look.
